There would have been a few choices.. The only fact I know for sure that may be what you're after is that it used a C6, not a C4, and that was the stubby C6 housing, not the long streamlined one put behind 429s.

My '73 351C came from the factory with an FMX.

My 73Mach1 351 left Dearborn with an FMX as well, but I'm using a C4 at the moment & it seems to be coping fine.

In addition to C6 and FMX, they did also use the C4, my brother has one factory-installed in his '72 351C 2V Torino. This assumes you are only talking about automatics, they also came with 3 and 4 speed manuals too.

Interesting. So assembly line managers could pick whichever was available, C4 or C6? I can see how both would work fine, but I'd just assumed a choice was made, and managers stuck with it.Or maybe Stangs got the C6 and Torinos the C4? Or maybe it depended on the plant?

I'm just trying to figure out what kind of car to be looking for to find a donor 9 inch and C-6 to put my 429 in. I had been told all 351C cars had C-6 and 9 inch. It aint' gonna be as easy to figure out as I hoped. Thanks all, Mike

If I am not mistaken the 351C in these year models all used the small block bolt pattern, so this transmisson would not work behind your 429.

Maybe one of the fellows that mess with the 351C will verify this.

You would need a trans from a non-lincoln chassis, no T-birds or Marks, as they use the oddball long tailhousing with a straddle mount.

Good info Hemi, but what's the problem with a T-bird tranny? My conversion's not-running yet, but I've got a 429 and C6 from a '70 Thunderbird sitting on a tranny mount from a 351C C6. Sure thing the mount is not the same as the original T-bird one, but apparently it fits OK - according to my mechanic. Should I slide on under there and check it out?

Actually, I've just remembered. Last year I spent some time under a 71 Drag Pack Stang with a C6. That had the long tailhousing too, and what I think was a standard Stang C6 mount. (I didn't pay it any attention, which suggests there was nothing unusual about it.)

Hemikiller,

The 351C-4v also came backed by an FMX, at least that is what is in my 70 Torino GT.
